are substituted in place of the lever and sprlng.

Similar letters of reference indicate like parts throughout the several views.

In reference to the construction shown in Fig. 1, a pivoted lever a is mounted on the body of the device and is adapted to actuate a plunger 6, sliding in the body of the shell casing 0, so as to force an inlet valve (Z from its seat and allow the high pressure aerated liquid to pass from the bulk receptacle supply 6, through a passage 39, to the intermediate measuring vessel or container 7". The plunger Z) is provided with a cup leather 6 to insure a liquid tight sliding fit with the bore in which it works. This container f is provided with a snifting device f consisting of a long tube 9 with an interior rod 9 having a valve seat 9 at the upper end, and a wedge shaped portion 71. at the lower extremity. This wedge h is engaged by the first, 2', of a pair of inclined cams or slopes on the plunger 6 when it is desired to lift the valve from ofi the seat at the top of the snifting tube 9, the said valve being normally maintained thereon by gravity thus preventing the escape of the gas given off from the incoming charge of aerated liquid. An outlet valve 3' is fixed at the bottom of the container 7, the guide of which is wedge shaped at the lower extremity and is adapted to engage in the second cam or slope is of the plunger 6. The spring 4% normally retains the valve j upon its seat so as to prevent the liquid from escaping from the container The valve (Z is opened when the lever a is pushed into the position a? and when it is drawn back to positions y and z, the wedge h of 'the snifting device 7 is pushed up, and the valve is pushed off its seat 9 the accumulated high pressure of gas in the dome of the container 7 thus escapes down the tube 9 to the exit orifice 2' to the atmosphere, while when the lever a reaches the z position, the outlet valve 7' is raised and the aerated liqquid falls ig to the glass, through the nozzle 1% without any violence at atmospheric pressure only. A spring 1" contained in the casing 0 acts upon a collar on the plunger 1) in order to insure prompt closing of the valves 72, and when the lever a is released. The lever a is maintained in the quiescent position shown in the drawings, by virtue of the pressure acting on the valve cl being greater than the force exerted by the spring 1", this insures the valves being normally closed and so obviating leakage.

In Fig. ,,3, I illustrate an alternative device for producing the same result by means of a screw thread cut on the spindle 6 working in the casing c and fitted with a hand wheel Q or other suit-able arrangement. The spindle 5 is provided with cam slopes i and it in the form of grooves, and when the same is screwed in by revolving the hand wheel 9', the snifting valve is closed on its seat 9 while the valve 7' is disengaged from the cam slope is, and is closed by the action of the spring m. The end of the spindle 6 now presses against a deformable diaphragm (Z arranged at the end of the valve (Z, so as to make a liquid tight joint at that part of the casing. A further movement of the spindle 6 causes the valve (5 to disengage from its seat and to allow the highly charged aerated water to pass along the passage 7? to the intermediate vessel f as before. On reversing this action, the spindle b is withdrawn, the supply valve (Z is closed and the cam slope 2' lifts the valve wedge 71- thus allowing the compressed gases in the dome of the measuring container f to escape down the snift tube 9 and discharge passage 2' F ig. 2. On continuing this reverse movement, the cam slope is raises the discharge valve allowing the water to fall through the nozzle a into the glass at atmospheric pressure. I also fix as a convenient adjunct a small control valve 8, which controls a passage t leading to the high pressure supply and is provided with a needle jet n through which a fine stream of highly charged aerated liquid can be drawn off direct without passing through the snifting valve already described. This stream of highly charged aerated water is found necessary for thoroughly mixing thick syrup or other flavoring materials before adding the low pressure soda water from the container f.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent I 1. Apparatus for the delivery of high pressure liquid from bulk consisting of in combination, a valve for controlling the supply of liquid from bulk, a measuring chamber for receiving such supply, a snifting valve for snifting the gaseous pressure from the said measuring chamber, a discharge valve, a sliding plunger adapted to work in the body of the device, surfaces on said plunger adapted to engage and operate said valves sequentially during the stroke of the said plunger and hand operated means for actuating the said plunger, substantially as described.

2. Apparatus for the delivery of high pressure liquid from bulk, consisting of in combination, a valve, for controlling the supply of liquid from bulk, a measuring chamber for receiving such supply, a snifting valve with wedge shaped stem, a measuring chamber discharge valve with wedge shaped stem, a sliding plunger adapted to work in a liquid tight manner in the body of the device and to coact directly with the said high pressure discharge valve, cam surfaces on said plunger adapted to coact sequentially with the snifting and low pressure discharge valves and hand operated means for actuating said plunger, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
